Question

Quizplus · Accepted Answer

The most certain technique to determine the existence of the mutation in an unborn child is through amniocentesis. This involves analyzing a small sample of the amniotic fluid surrounding the fetus, which contains genetic material from the developing fetus. It can reliably identify sex-linked disorders by analyzing the sex chromosomes (X and Y) of the fetus. Ultrasound, IVF, and germline therapy do not involve direct analysis of genetic material and therefore cannot provide certainty about the presence of a sex-linked disorder.
